J. STEOKER & F. G. NORDMANN DEVIGE FOR OPERATING RAILWAY GATES.

UNITED STATES PATENT OFFICE.

JOSEPH STEOKER AND FRIEDRICH G. NORDMANN, OF LEXINGTON,

KENTUCKY.

DEVICE FOR OPERATING RAILWAY-GATES.

- SPECIFICATION forming part of Letters Patent No. 463,205, dated November 17, 1891.

Application filed June 2,1891.

To all whom it may concern.

Be it known that we, J OSEPH STEOKER and FRIEDRICH G. NORDMANN, citizens of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented certain new and useful Improvements in Devices for Operating Railway-Gates; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to devices for operating railway-gates; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed,

whereby the gate is opened and closed 'by the train.

This device is applicable to short mineral zollines in mining districts, over which small trucks run by gravity, wire traction-ropes, &c., and for use in drifts and in mines and in all other places in which railways are used and to which it may be found adapted.

In the drawings, Figure l is a plan view of the devices, and 2 is a side view of the 53,1116.

A are the rails of the railroad, and B is a gate hinged to the gate-post O in the ordinary manner. The gate 0 closes across the roadway D, which crosses the rails A. In order that the gate may be closed by the train be fore the train reaches the crossing, the said gate is provided with a projecting arm I).

E is a cord, wire rope, or chain, which is connected to the end of the arm I).

F is a barrel mounted on the shaft f, which is journaled in the brackets f, secured to the road-bed between the rails A.

G is a toothed wheel journaledon the shaft f, and g is a friction-clutch which connects the toothed wheel to the said barrel.

G is a spring which presses the halves of the friction-clutch together,so that thetoothed wheel will revolve the barrel unless the rope E offers a considerable resistance.

II is a toothed rack secured to the under side of the truck h or to any other vehicle traveling 011 the rails. Each car is provided Serial No. 394,873. (No model.)

are arranged in line with each other, so as to form a continuous toothed rack. When a train comes to the toothed wheel, the racks gear into the toothed wheel and revolve the barrel, thereby winding u p the cord or chain and closing the gate across the roadway.

A second barrel similar to the barrel F is mounted on a shaft f and secured between the rails on the other side of the gate from the first barrel. This second barrel is provided with a cord connected to the arm on the gate, and a friction-clutch is provided for connecting the barrel to a toothed wheel on the barrel-shaft exactly the same as hereinbefore described. hen the train has passed over the crossing, the racks engage with the toothed wheel connected to the second barrel and thereby open the gate, at the same time partially unwinding the cord from the first barrel. desired distance from the crossing, so that the gate may be closed before the train reaches the crossing.

When the gate is closed, it strikes against the post i, and the f liCtlOi1Cl1ll3Ch permits the toothed wheel to continue to revolve without turning the barreland breaking the cord.

IVhen the gate is thrown wide open, it strikes against a spring t", secured to an arm on the gate-post or to any other stationary supsudden shock.

The drawings show only one line of track and one gate adapted to be closed across the crossing by uptrains which approach the crossing from the right hand. The other line of track, which is not shown, is provided with a similar gate and operating mechanism, which parts are in all respects a duplication of the devices hereinbefore described; but the said other line is arranged for the down'trains, which approach from the left, and its gate is therefore turned in the reverse direction.

What we claim is-- 1. The combination, with a gate provided with a projecting arm and fixed stops for the gate to open and close against, of a barrel provided with-a flexible cord or chain connected to the said arm, a toothed wheel on the barrel-shaft, a spring-pressed friction-clutch The barrels may be arranged at anyv port, so that the gate maybe relieved from connecting the said wheel and barrel, and a connecting the said wheels and barrels, and a toothed rack adapted to be secured to a travtoothed rack adapted tobe secured to a travcling truck and to engage with the toothed cling truck and to engage with thetoothed wheel and operate the gate, substantially as wheels and'operate the gate, substantially as and for the purpose set forth. 1 and for the purpose set forth.
